WATER-H EATING APPARATUS.

SPECIFICATION forming part of Letters Patent 110,364,181, dated May 31, 1887.

Application filed July 13, 1886. Serial No. 107,856. (No model.)

To all whom it may concern:

Beit known that I, J OSEPH Love, of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in WVater-Heating Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention is an improved water heating apparatus of that kind in which heat is supplied by a gas or lamp burner, and in which a water-supply under pressure is obtained from a city supply system-or other source, the device herein shown as embodying my invention being more especially intended for supplying hot or warm water for basins or bath-tubs in place of the hot-water supply apparatus commonly employed in dwellinghouses.

The invention consists in the matters hereinafter described, and pointed out in the appended claims. I

A device embodying my invention comprises as its essential features a tank or re ceptacle for water connected by a valved passage with the watcr-supply system of the house, and provided with a valveless or open exit-pipe having a suitably arranged dischargeorifice, and agas burner or lamp,which is located beneath said vessel or. receptacle for heating the latter. In this device the water in the heating-receptacle is not confined, as in waterheating devices heretofore used; but, 011 the contrary, the top of the receptacle communicates with the open air through the said disehargepipe, a valve for controlling the discharge of the water being located in the supply-pipe leading to the receptacle. By this construction the use of a heavy or strong receptacle for the water is rendered unnecessary, and the heater may therefore be readily and cheaply applied in any place where it is desired for use.

The invention may be more readily under stood by reference to the accompanying drawings, in which- Figure 1 is an elevation, with parts in section, of a water-heating device embodying my invention. Fig. 2 is a similar elevation illustrating another form of the said device.

In the said drawings, A indicates the watersupply pipe; B, the heating receptacle or tank, which is connected at its lower part with the water-supply pipe A; G, a valve 1n said water-supply pipe; D, a gas or other burner located beneath the receptacle B; E, an exit-pipe leading from the top of the receptacle and provided with a nozzle, 0, from which the water is delivered as required for use.

The device is shown in Fig. 1 as adapted to supply hot water to a stationary basin, F, having the usual cold-water faucet, G, connected with a water-supply pipe, G, of which the supply-pipe A of the heating-receptacle 1s a branch. The discharge-nozzle c of the exitpipe E is in this instance connected with a tubular faucet-standard, E, fixed in the top f of the basin-casing, and connected by means of a vertical tube, E, with the tube or pipe E, which is immediately connected with the top receptacle, B. In this case the valve G is actuated by means of a vertical valve-stem, O,extending from the valve upwardly through a tube, E*, which is connected with and forms a downward continuation of the connectingtubc E",and through the said connecting-pipe E and faucet-standard E, said valve-stem being provided above the standard with a handle, C by which the valve-stem may be readily turned for openingand closing the valve.

As aconvenient form of valve for use in connection with the particular construction of the parts described, I employ a globe valve provided with a horizontal diaphragm, c, in which the valve-seat is formed, and having a conical plug, 0, for closing said aperture, said plug being secured at the lower end of the stem G, which latter is threaded at oto engage a correspondiugly-threaded aperture in a plug, 0, which is connected with the top of the valvecasing, and is preferably provided in its upper end with a screw-threaded socket. 0, receiving the lower end of the tube E, and thereby forming a coupling-piece connecting said tube E with the valve-casing. The tube E being in this construction connected with C in the supply-pipe.

the discharge passage or nozzle of the apparatus, any packing at the point at which the valve-stem enters the valve-casing is obviously unnecessary, inasmuch as when the valve is opened,so as to give a pressure within the part of the valve-casing through which the valvestem passes, the water will be forced through the receptacle and exit-passage, and will, by filling the tube E give a back-pressu re in said pipe. To prevent leakage of water at the point at which the va1ve-stem 0' passes through the top of the faucet-standard E,a gland packing-ring, e, is preferably therein provided, as clearly shown in the drawings.

In the operation of the device constructed as above described, water is forced from or through the receptacleB by openingthe valve Upon closing the valve the receptacle will obviously remain full of water, and the water therein will usually be heated preparatory to its discharge by allowing the flame from the burner D to act upon the bottom'of the receptacle for a necessary time. After the Water within the receptacle is snfficientlyhot, the valve is opened and the hot water discharged from the receptacle by the pressure of the inflowing cold water. It is of course obvious that water flowing continuously through the receptacle will be heated to a greater or less extent, according to the abundance of the flow and size of the heatingfiame, so that by properly regulating the valve a continuous supply of warm water may be obtained. The size of the receptacle will of course be varied as may be necessary for the particular purposes for which the device is to be used, and a larger or smaller burner or more than one burner may be employed, as found necessary to heat a required quantity of water. 7 r

In order to facilitate the heating of the water flowing into the receptacle, I preferably extend the supply-pipe A through the side of the said receptacle and provide said pipe with downwardly-directed exit opening or. orifice (0, arranged to discharge the water toward and against the bottom of the receptacle, as clcarl y shown in Fig. 1.. By this construction the rapid and continuous heating of all the Water is insured, inasmuch as the water flowing from the supply-pipe is thereby brought into imme diate contact with the part of the receptacle directly exposed to the burner-flame.

In Fig. 2 I have illustrated a somewhat different and more simple construction of a device embodying the main features of my invention. In this case the valve 0 in the supply-pipe A is a simple rotating plug-valve, and the exit-pipe E at the top of the receptacle B consists of a tube bent to form a suitable discharge-nozzle. One important advantage obtained by the heating device above described is that the water-pressure from the supply-pipe is usually shut off from the receptacle and the latter is always in communication with the open air, so that an extreme or dangerous pressure can under no possibility occur in the said receptacle, and the necessity for any great strength in the latter to obviate liability of leakage or bursting isentirely avoided.

I claim as my invention- 1. The combination, with a heating tank or receptacle, of" a water-supply pipe connected with said receptacle, a valve in said supply- I pipe, a gas orother burner located beneath the receptacle, and an exit-pipe connected with the said receptacle, said exit-pipe having constant communication with the outer air, whereby the water passing through the'receptacle may be heated without producing any steam-pressure therein, substantially as described.

2. The combination, with a heating tank or receptacle, of a watersupply pipe communicating with the receptacle, a valve in said supply-pipe, an open exit-pipe connected with the receptacle, a gas or other burner-located beneath the receptacle, a faucet-standard, E, provided with a nozzle, e, and communicating with the said exitpipe, a tube, E, connected with the said faucetstandard and with the casing of the said valve, and a valve-stem passing through the faucet-standard and tube E and connected with the valve for actuating the latter, substantially as described.

3. Therombination, with a heating tank or receptacle, of awatersupply pipe extending into the lower portion thereof, and having a downwardlydirected discharge-orifice, a valve in said supply-pipe, an exit-pipe connected with the top of said receptacle, said exit-pipe having free communication with the outer air, and a gas or other burner located beneath the receptacle, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence two'witnesses.

JOSEPH LOVE.
